Schwann Cell

Glial cells of the peripheral nervous system that form the myelin sheath around axons, insulating them and enhancing the speed of nerve impulse conduction.

Key Functions:

• Forms myelin sheath around axons in the PNS.
• Increases the speed of nerve impulse conduction.
• Aids in regeneration of damaged axons in the PNS.
• One Schwann cell myelinates a single segment of an axon.

Interacting Systems & Components:

• Glial Cell (type of)
• Myelin (produces)
• Axon (myelinates)
• Neuron (supports)
• Peripheral Nervous System (located in)
